Fruit and Vegetable Prices Are Rising

Grocery shoppers may soon need more green in their wallets to afford their next salad.

The cost of fresh produce is poised to jump in the coming months as a three-year drought in California shows few signs of abating, according to an Arizona State University study set to be released Wednesday.

The study found a head of lettuce could increase in price as much as 62 cents to $2.44; avocado prices could rise 35 cents to $1.60 each; and tomatoes could cost 45 cents more at $2.84 per pound. (The run-up in produce prices is in line with other projections showing that overall food cost gains are expected to accelerate this year.)

The latest projections were compiled by Timothy Richards, an agribusiness professor at ASU’s W.P. Carey School of Business. He studied the drought’s effect on farmland and consumer purchasing trends to determine the eight fresh fruits and vegetables likely to see the largest price increases this spring and summer.

And the price increases may already be happening. Grocery prices rose by 0.5% for the second-straight month in March, according to the Labor Department’s consumer-price index, released Tuesday. It was the largest two-month gain in the food-at-home category since 2011. Fruit and vegetable prices rose 0.9% last month, after a 1.1% gain in February. Meat and dairy prices are also increasing. Meanwhile, overall consumer prices rose just 0.2% last month, as broader inflation in the economy remains tepid.

California is the largest domestic producer of each of the products Mr. Richards identified, ranging from grapes to peppers. And in the case of avocados, it’s the only state with a significant crop.
